Grokking GATK: Common Pitfalls with the Genome Analysis Tool Kit (and Picard)
Recently I’ve been following the GATK DNASeq Best Practice Pipeline for my limpet sequence data. Here are some of the mistakes I made and how I made them go away.
Status Report: October 2015
I’m still alive, here’s some things what I’ve done.
Size Matters
My datasets are so big, they trigger an NFS bug in the kernel
